Given below are two statement one is labeled as Assertion (A) and the other is labeled as Reason (R).

Assertion (A): is an example of allyl halide

Reason (R): Allyl halides are the compounds in which the halogen atom is attached to hybridised carbon atom.

In the light of the two above statements, choose the most appropriate answer from the options given below:
  1. (A)(A) is true but (R) is false✓ Correct
  2. (B)Both (A) and (R) are true but (R) is not the correct explanation of (A)
  3. (C)(A) is false but (R) is true
  4. (D)Both (A) and (R) are true and (R) is the correct explanation of (A)

Answer: (A)

Solution

The assertion is correct: is an allyl halide, since Cl sits on the carbon adjacent to the double bond.

The reason is false: in an allyl halide the halogen is on an sp carbon next to the double bond, not on an sp carbon of the double bond itself (that would make it vinylic).
